USA: Commercial Systems Dominate Californian Solar Thermal Market

Submitted by Baerbel Epp on March 24, 2017
California Incentive ProgrammeThe California Solar Initiative (CSI) – Thermal Program seems to have stabilised at around 20,000 m² (or around 200,000 ft²) of subsidised collector area per year. Commercial applications dominate the statistics, although there was a spike in the share of residential systems in 2016. The peak in applications for commercial pool heating in 2014 was due to the late addition of this type of system to the state subsidy scheme. It took almost a year before the level of incentives and other requirements were set, so that all the applications piling up over that period had to be processed in 2014. The data in the chart was provided by the California Public Utilities Commission (CPUC) and shows the subsidised and installed collector area for each year.

USA: Ups and Downs of Californian Incentive Levels and Application Numbers

Submitted by Baerbel Epp on August 25, 2015
USA California StatisticsIf there were an award for the most transparent support programme in the field of solar heating and cooling, then the California Solar Initiative (CSI) – Thermal Program would get the prize. The CSI-T programme offers a regularly updated and publicly available Excel file of all submitted, approved and paid applications, and this file also includes an amazing amount of additional information, such as collector size, system supplier, contractor for the installation, total project costs or the application itself. The chart above, provided by Lewis Bichkoff, Lead Analyst of the CSI Thermal Program at the California Public Utilities Commission (CPUC), shows the subsidised and installed collector area per year. The annual volume shows significant growth from 953 m² (10,247 ft²) installed and granted during the first year to 36,641 m² (394,401 ft²) in 2014. In 2014, there was a noticeable dominance of pool heating systems, which made up 71 % of the total subsidised collector area.

Guide to Solar Thermal Incentives in Washington DC (2012)

Submitted by Raquel Ponte Costa on June 21, 2015

This report from the District Department of the Environment, Washington DC’s local environmental agency, details how local citizens can use the city’s Renewable Energy Incentive Program (REIP) to receive incentives for using solar thermal systems. Further information on solar thermal incentives worldwide can be found here.

Overview of Solar Water Heating Inputs, Data Sources, and Potential Study Results (2012)

Submitted by Raquel Ponte Costa on June 20, 2015

This report comes from The Cadmus Group, and provides information on the organizations research into and plans for expanding the use of solar thermal water heating throughout the Pacific North-West United States. It is a good example of how businesses are approaching the solar thermal market moving forward, and what successes and obstacles they see in the future.

2009 Updates and Trends – IREC

Submitted by Raquel Ponte Costa on June 14, 2015

This report was from the Interstate Renewable Energy Council (IREC) Annual Meeting in October, 2009. The report is broken down to cover state incentives & policy trends, solar installation trends, net metering & interconnection updates & trends, and workforce development and training. For current policies that are mentioned to withstand solar growth, they mention the Energy Improvement and Reinvestment Act (part of the federal “bailout bill” in 2008) and the American Recovery and Reinvestment Act (part of the “stimulus bill” in 2009).

Unparalleled Life Cycle Savings: Solar Thermal Technology and Condensing Boilers (2012)

Submitted by Raquel Ponte Costa on June 7, 2015

This white paper was written by Sutherland D. Junge of Unical/Lattner. It presents the case for using the combination system of solar thermal and condensing boiler technologies (STaCB), and focuses on the cost savings of these systems. STaCB systems can be used for a wide variety of applications, including in-floor radiant heating, swimming pools, snow melting and domestic hot water systems. The presentation concedes that the upfront capital costs of installing a STaCB system is greater than the initial price of installing a more conventional solar thermal system.

Guidelines for Determining the Tax Credit for Investing in Renewable Energy Property (2014)

Submitted by Francesco Gattiglio on October 7, 2014

This document provides information and guidelines on tax credits resulting from investing in renewable energies in North Carolina. It provides a legislative background of the issue dating back to 1999 as well as punctual information on credit ceilings, definitions, eligibility, requirements, frequently asked questions and tax credit amount for each type of renewable energy considered.

USA: California Solar Initiative to Add Technologies to Eligibility List

Submitted by Baerbel Epp on June 13, 2013

The California Solar Initiative (CSI) is further extending the number of system types eligible for its CSI – Solar Thermal programme. Already in December 2012, California’s Governor, Edmund Brown, signed a law stipulating that solar heating of commercial pools is to be incorporated into the subsidy scheme. In March 2013, the California Public Utilities Commission (CPUC) published the Final Decision, specifying that solar cooling, space heating and process heat systems should be eligible technologies within the CSI – Solar Thermal. The CPUC, however, still has to work out the specific rule set, something which might delay implementation. The pie chart shows the share of system suppliers within CSI by the end of May 2013. By then, the programme’s administrators had received 1,400 grant applications, half of which had included the system supplier’s name.

Solar Water Heating Systems: A Review of Global Experiences (2010)

Submitted by Raquel Ponte Costa on May 29, 2012

Prepared jointly by India’s Ministry of New and Renewable Energy (MNRE) and the Renewable Energy and Energy Efficiency Partnership (REEEP), this report gives an overview of the Solar Water Heating Systems (SWHS) market in India over the last decade, and counterpoints it against broader global developments. After looking at global trends in market development, the document gives summaries of UNDP-GEF and REEEP experiences of SWHS projects. This includes summaries of specific projects over the last five years.

Solar Thermal in Spain (2007)

Submitted by Raquel Ponte Costa on July 16, 2009

This document produced by the Spanish IDAE (Instituto para la Diversificación y Ahorro de la Energía) in 2007 explains what is solar thermal energy, its benefits and applications, providing at the same time practical information like for instance the incentive programmes existing in Spain (for both single family houses and hotels) and the prices of solar thermal equipment.
